News for hackers. Stuff that matters.

Actually it's something like a researcher-focused app that allows you to open Jupyter notebooks, code snippets, PDFs, right next to the chat window pane.

Let's say you're working on protein design and you want to view the 3D structure of the protein, you can have the agent build a pane for that in the app, and you can ask the agent to help customize it as well.

It has a chat interface, but also lets you split the window into different sub-windows that can open different interfaces, like a Jupyter notebook (with a working kernel), a code editor, or a file browser. You can also ask the agent to create custom interfaces, like a protein structure visualizer, or an SQLite viewer, or just a simple place to manage your citations.

Under the hood it's running on your local Claude Code instance, I'll probably be adding support for other APIs through Open Router soon.

Yup, the layouts and panes are persistent and also have state.
I believe currently it would work if you've already set up the MCPs via Claude Code, because it's running off your local Claude Code under the hood. But I'll look into surfacing the MCPs like in the Claude app.
Thanks for sharing emacs + gptel! I'll find some time to try it out
By checkpoints do you mean versioning and rollback?
Yeah I know people who think that chat is the last UI we'll ever need, but I really think there's so much that can be done with malleable interfaces.
The demo and videos are really cool! Just a few guardrails might make this a lot more usable as an actual IDE.
I will! Thanks for the rec
Hi HN, I built Panel because research work means switching all the time between a chat with an agent, the papers I'm reading, the notebook I'm running and the data files I'm looking at.

Panel is a local web app with dockable panes made with dockview. You get chat, files, PDFs, markdown and Jupyter notebooks.

The agent can also create custom panes on request, like a protein structure viewer or an SQLite browser.

There's also an early "Module" system. Modules are like Skills, but with typed inputs, outputs and intermediates, so a long job shows its progress and its results can feed the next step. Right now the working one is a literature review, with an early version for hypothesis generation.

How it's built: a Vue + dockview frontend and a Python (FastAPI) sidecar that drives the agent backends. Everything runs on your machine.

Honest limits for now: - Full support is Claude Code only, so you need it installed and signed in. Codex and other harnesses are not supported yet. - Still very rough around the edges, I've been adding to it as I use it myself. Feedback welcome!

Show HN: Testreel – Programmatic product demo videos from JSON and Playwright

https://github.com/greentfrapp/testreel

I made Testreel as a programmatic alternative to ScreenStudio.This has two primary value props: 1. Not having to manual re-record a demo because of a typo or misclick; just update the config and regenerate 2. Allows LLM agents to generate demo videos for your web app, complete with cursor overlay, and a customizable desktop backgroundTestreel is an npm package that lets you describe...

Re:Ask HN: What Are You Working On? (October 2025) on Sunday October 12, 2025 @10:48PM (#45564254)
I've been working on https://booplet.com. It's like Lovable but for desktop apps and heavily inspired by Robin Sloan's home-cooked app essay [1][2]. The idea is to let anyone, especially non-technical folks, build and use personal apps. Instead of cloud deployment, we focused on a local-first setup so that users can fully own their apps and data.

Show HN: Stores, a library to make tool use simple

https://github.com/silanthro/stores

Hi HN! While building agents for various use cases, we found ourselves copying and reusing code for common tools. To help with that, we decided to create a Python library to simplify tool use across different providers and packages, as well as start a public collection of tools that anyone can use!

Hi HN! Vispunk.com is our early prototype towards an image-first approach for AI-based image creation and editing.

Our goal is to make it simple and intuitive to compose an image with visual assets instead of just text i.e. photobashing.

To help with this, we've made img2img the default workflow, along with tools that generate PNG stock images and human poses.

We've also incorporated early versions of familiar Photoshop tools like Generative Fill, Remove Background and Object Select.

Check out our subreddit at r/vispunk for more details! And for those interested in contributing to development, keep an eye on https://github.com/vispunk/vispunk-webui.

Hi HN! Co-founder of Dashibase here and we're launching Dashibase Insert today as a free tool for Supabase users.

After chatting with a lot of our users (thanks for your time!) we've got a series of cool tools lined up for Supabase users! We'd love to hear your thoughts about these tools and your feedback/suggestions.

First up, a Notion-like form builder! Inspired by Notion and Tally, this form-builder plugs right into your Supabase projects.

Check out https://dashibase.com/insert for a demo and sign up for a free account!

If you already have a Dashibase account, simply log in with the same account details at https://insert.dashibase.com.

Happy form-building! We'll be here for any feedback/bug reports/suggestions. Or join our Slack!

PS - for the curious reader, we also shared our thoughts on Notion's UI in a blog post at https://dashibase.com/blog/notion-ui/

Hi HN!

This is for those of us who really hate building user dashboards and login UIs.

And for those of us who have to use ugly dashboards everyday.

We recently open-sourced our dashboarding tool for Supabase users at https://github.com/dashibase/dashibase, made with Vue and Tailwind.

It makes building both product and admin dashboards really simple - you just need a config file to specify Supabase credentials and the table views.

Out-of-the-box features at the moment:

- Authentication UIs including sign in and sign up (third-party support coming soon)

- CRUD features with simple form validation for required fields

- Caching of dashboard locally to reduce queries and latency

- Responsive dashboard - desktop, tablet, mobile

If you find this useful, consider joining our beta at https://dashibase.com!

Hi HN! We've been using Supabase for awhile thought it'd be great to have a no-code app that plugs right into Supabase to help with creating dashboards.

So we came up with Dashibase! You just need to specify your Supabase URL, anon key + the tables you want to expose to your user and out pops your dashboard.

We are open for beta access now and looking to validate this idea with an initial group of 25 users (see https://dashibase.com).

Questions and comments welcome!

Oh could you give it a try now? I just woke up and got around to fixing some of the scaling issues - it's not perfect but at least it's only failing 5% of queries when I load-tested with locust. Will get around to better fixes later!
Thanks everyone for the HN hug of death on this little side project of mine! It's been crazyyyy. And if it's okay I also just wanted to give a small shout out to my other project at https://catche.co - we've got about 30 people on that waitlist, check it out!
Oh nice high five! Plus that's the smart way to do it like oh_sigh mentioned in their comment too
Ahh this is actually a really really good point - I just pulled this out of my butt today as a fun coding project haha but what you described would be a much smarter way to do it. Less fun though! Oh well I'll just leave this up, I'm guessing the traffic will probably die down after awhile.
